using the WKB expansion upto any power of \hbar could we writte the path integral as
I_{WKB}(1+ \sum_{n=1}^{\infty} \hbar ^{n} I_{n})
where the symbol 'WKB' means the semiclassical approximation and the I(n) can be calculated approximately.
the idea is to compute Feynmann integrals as a series (divergent ?) on power involving \hbar
